Though some studies have found valerian to have a subjective mild sedative effect in improving sleep,3 others have found there to be no objective statistical significance between valerian and placebo.5 Similarly, some research revealed that valerian reduced objective sleep latency when provided for an acute period of 3 days,4 while one study discovered that it takes about 2-3 weeks before valerian effectively begins to work.1 The latency period becomes a limiting factor in the effectiveness of the research assessing valerian, for not all studies spanned 14 days or more.5
